る。Since the present invention is constructed as described above, it has the following remarkable effects. (1) Since the plurality of projecting supports are arranged in the horizontal transport device at intervals, the article to be coated placed on the device is separated from the surface of the device and at the tip of the support. It is held while making contact. Therefore, unlike the conventional example, the surface of the article to be coated is almost exposed, so that the electrostatic powder coating is applied not only on the upper surface of the article but also on the side surface and the lower end surface side. Therefore, the outer surface of the object to be coated can be entirely coated. (2) Since the vertical movement device that separates the protruding support from the object to be coated is provided, the plurality of protruding supports holding the object to be coated are sequentially separated from the object to be coated in the separation area. Therefore, the contact portion of the object to be contacted, which comes into contact with the tip of the projecting support, can be surely coated, so that more complete coating is possible. (3) Since the belt cleaning device is provided at the end of the horizontal transport device, the overspray powder adhering to the conveyor can be completely removed to clean the conveyor, and the removed overspray powder can be collected. It can also be reused. (4) Since the coating booth is provided with the air supply chamber having the porous inner wall, the overspray powder does not adhere to the inner wall when air is jetted into the coating space from the hole of the inner wall. (5) Since the belt conveyor and the projecting support are made of an insulating material, the electrostatic powder paint can be more effectively attached to the object to be coated.
